秸秆还田替代化肥对黄土旱塬小麦产量及水肥利用的影响

open access: yesShuitu Baochi Xuebao, 2022
为研究不同秸秆还田量替代部分化肥后对黄土高原冬小麦产量、水肥利用效率和硝态氮积累特征的影响。于2018—2021年在晋南黄土旱塬冬小麦种植区,设置秸秆不还田(S0)、秸秆半量还田(S1/2)、秸秆全量还田(S1)、秸秆2倍量还田(S2)4个还田量处理,研究不同秸秆还田量替代化肥对冬小麦产量形成、水肥利用效率及土壤硝态氮残留的影响。结果表明:在黄土旱塬麦区,秸秆还田替代8.3%~31.9% N和15.7%~63.2% P2O5的基础上,冬小麦产量总体随秸秆还田量增加而增加,且在降水丰沛年份 ...

玉米秸秆粉碎还田对黑土坡面土壤侵蚀特征的影响

open access: yesShuitu Baochi Xuebao, 2022
为探究玉米秸秆粉碎还田对黑土坡面土壤侵蚀特征的影响,对不同坡度(3°,5°和7°)下不同玉米秸秆粉碎还田量(0,25%,50%,75%和100%)坡面进行人工模拟降雨试验。结果表明:玉米秸秆粉碎还田措施具有调控径流作用,坡面产流时间延缓,产流率和径流量降低;秸秆还田量越大,产流时间延后越明显,平均径流流速越低;在3°坡面,秸秆粉碎还田25%和100%处理的调控径流效果较好,在5°和7°坡面,秸秆粉碎还田50%和75%处理的调控径流效果较好。同时 ...
